In a sludge treatment installation, a movable carriage is arranged transversely above a work surface of a floor. The movement of the carriage by longitudinal translation over the floor is initiated by a first drive shaft carrying a toothed wheel meshing with a drive chain. A second chain helps to guide the carriage. On the carriage is provided a rotary turning tool which engages in the sludge. Driven in rotation by a second drive shaft independent of the first, it includes pairs of semi-cylindrical paddles fixed substantially symmetrically by one of their edges on either side of a shaft driven by the second drive shaft. The two paddles in each pair of paddles are asymmetrical as a result of having different radii, with a difference at least equal to about 5%. Forced ventilation acts directly on the paddles.

The present radiation source assembly is configured such that the distal portion of the radiation source is cantilevered with the respect to the distal portion of the protective sleeve in which it is disposed. This feature obviates the need to use spacers, stops, springs and the like in a distal portion of the protective sleeve to maintain correct position of the radiation source within the protective sleeve. Further, the present radiation source assembly is advantageous in that allows for withdrawal of the radiation source from the radiation source assembly without the need to disengage all of the components. Thus, it is possible to replace a single radiation source by removing it from the protective sleeve during operation of the fluid treatment system. This operation can be accomplished quickly without the need to shut down the fluid treatment system or otherwise compensate for the fact that one of the radiation source is being serviced.

Method and apparatus for treating materials using electrodeless lamps

Номер: US20120161031A1
Автор: David Richard Necamp
Принадлежит: Individual

The output wavelengths of an electrodeless lamp are controlled by passing a fluid over the surface of the lamp to control its temperature. The stabilized temperature prevents thermal runaway of the lamp and stabilizes the output wavelengths of the lamp. When the fluid passing over the lamp is water, the lamp can be used for sanitary treatment of the water. The treatment can be enhanced by shaping the electrodeless lamp to provide maximally effective water treatment.

In a memory unit 6, there is stored a correction table for each candidate value of an output set value of each of LED units 2. If UV rays have ever been emitted so far by the LED units 2, each of which is formed of a plurality of LED chips 8, then a PLC 5 acquires, upon setting of a output set value by an operation unit 53, a correction value corresponding to a cumulative emission time up to a previous emission, from the correction table of the output set value. Thereafter, the PLC 5 sets the magnitude of the power supplied to each of the LED units 2 using the acquired correction value. If an output set value different from a previous output set value is set, the PLC 5 obtains the correction value starting from the cumulative emission time upon modification. As a result, the UV irradiation apparatus enables power consumption necessary for emission of UV rays to be reduced, and UV ray output to be kept constant regardless of the cumulative emission time, even if the output set value is modified.

Method and device for biological wastewater purification

Номер: US20130015125A1
Автор: Kurt Ingerle
Принадлежит: Individual

The present invention relates to the biological purification of wastewater by means of activated sludge, wherein the wastewater is first introduced into an activated-sludge tank (B tank) that can be ventilated and then is introduced into one of two sedimentation and recirculation tanks (SU tanks) in alternation, the sedimentation and recirculation tanks being continuously connected hydraulically to the B tank. In the sedimentation and recirculation tanks, the activated sludge and the treated water are separated by sedimentation (V phase), and thereafter activated sludge is fed back into the B tank (S phase). Then the contents of the SU tank are mixed (U phase). Finally, the treated water is drawn off (A phase). The cycles in the SU tanks are phase-shifted and the A phases border on each other so that there is flow through the SU tanks only in the A phases, an approximately constant water level is present, and thus a wastewater treatment plant discharge corresponding to the wastewater treatment plant supply develops (continuous flow principle). In order for the thickened sludge fed back from the SU tank into the B tank not to flow back into the SU tank (S phase), two ventilation fields are provided in the B tank, wherein in the S phases, only the ventilation field adjacent to the SU tank in which the S phase is miming is operated.

Methods for the treatment of ballast water

Номер: US20130056648A1
Автор: II Richard W. Fahs, Matthew D.W. Fahs
Принадлежит: Fahs Stagemyer LLC

A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. This process can be used for the remediation of water, particularly ballast water.

The concentrated compartments and the diluted compartments are formed by successive alternatively arranged oppositely charged ion exchange membranes between two electrodes. A brine solution is fed into the concentrated compartments, and a diluted solution is into the diluted compartments, the salinity of the diluted solution being lower than the salinity of the brine solution. Ions from the brine solution in the concentrated compartments pass through the membranes to the diluted solution in the diluted compartments forming a diluted brine solution in the concentrated compartments. The brine solution is extracted from the concentrated compartments for disposal. An electrical energy is produced due to the concentration difference of the brine solution and the diluted solution.
